Vertebroplasty and kyphoplasty are minimally invasive methods for treating stable vertebral fractures due to osteoporosis or metastases.
A needle is advanced through the skin into the collapsed vertebral body and bone cement is injected through this to obtain internal stabilization. This often leads to immediate pain relief. Kyphoplasty involves additional elevation of the collapsed vertebra by means of a balloon placed in the vertebra. The elevation is intended to prevent further collapse of the vertebral body and deformity of the spine.
For affected patients, these methods offer major long term advantages compared with conventional fusion operations.
In osteoporosis, the reduction in bone density can result in collapse of the vertebral bodies. The vertebrae can be stabilized by kyphoplasty /vertebroplasty (cement injection) under anesthesia in the operating room.
